Can I Get A Little Help Here?
1 answer:
Hey there :)
We know the formula for simple interest is
I = prt
{ The picture includes what each stands for }
Lehena:
Initial amount = $100
Interest rate = 2.5% =
Time = 3 years
I = ( 100 )( 0.025 )( 3 )
= 7.5$
Total = $100 + $7.5 = $107.5
Marty:
Initial amount = $100
Interest rate = 2% =
Time = 3 years
I = ( 100 )( 0.02 )( 3 )
= $6
Total = $100 + $6 = $106
How much more than Marty did Lehena receive?
= Total Amount of Lehena - Total Amount of Marty
= 107.5 - 106
= $1.5
Your answer will be option B) $1.50

Answer:

Step-by-step explanation:
In an arithmetic sequence the common difference d is
d = a₂ - a₁ = 10 - 8 = 2
To obtain the next term in the sequence add d to the previous term, that is
a₅ = 14 + 2 = 16
a₆ = 16 + 2 = 18
a₇ = 18 + 2 = 20
The next 3 terms in the sequence are 16, 18, 20
The n th term equation for an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = 2, thus
= 8 + 2(n - 1) = 8 + 2n - 2 = 2n + 6
